An undesirable side-effect of the operation of air conditioners in the hospital are acoustic emissions which can propagate as structure-borne noise or airborne noise in sick-rooms and function rooms. Despite useful information provided in DIN 1946 as well as in other relevant documents and legal statutes on restricting the acoustic emissions caused by air conditioning equipment, substantial noise phenomena are sometimes experienced in practice because of negligence in project engineering, installing and acceptance procedures. The air conditioning system of an ophthalmic hospital, exposing several rooms accommodating tumour patients of a Clinic of Radiology to substantial noise was studied to outline the problems involved in thresholds and indicative figures of noise comprising an essential low-frequency share as well as their particular annoying effects. It is recommended that the hospital hygienist should require the manufacturer and the fitter of an air conditioning system to present a special noise control certificate. The results of the investigation presented also serve to discuss hospital-specific and subject-related factors which can moderate the noise sensation of patients in threshold-relevant terms.
医院中空调运行产生的不良副作用是声发射，其可作为结构噪声或空气传播噪声在病房和功能室中传播。尽管DIN 1946以及其他相关文件和法律法规提供了关于限制空调设备产生的声发射的有用信息，但由于项目工程、安装和验收程序中的疏忽，实际中有时会出现严重的噪声现象。对一家眼科医院的空调系统进行了研究，该系统使放射科诊所几个收治肿瘤患者的房间暴露于大量噪声中，以概述包含大量低频成分的噪声阈值和指示数字所涉及的问题及其特别烦人的影响。建议医院卫生人员要求空调系统的制造商和安装人员提供特殊的噪声控制证书。所呈现的调查结果还有助于讨论与医院和受试者相关的因素，这些因素可以从与阈值相关的角度减轻患者的噪声感受。
